Application filed March '7, 1917. Serial No. 153,117.

To all whom it may concern Be it known that I, HAROLD JENNINos KITCHEN, a subject of the King of Great consequently obviates the necessity for any displacement of the vessel which receives the contents. 7

For this purpose, according to the invention, the furnace bed or other receptacle containing the molten metal is supported on friction rollers engaging with wheels running on suitably disposed rails, the wheels and rollers being so proportioned that as either spout, if there is more than one provided, is moved in one direction by the tilting of the receptacle to which it is attached,

it is moved in the opposite direction by, the

supporting wheels through the same horizontal distance. i

In the accompanylng drawing, Figure 1 represents in end elevation, and Fig. 2 represents in side elevation, partly in section on the line 2-2, Fig. 1, an example of an arrangement according to the invention as applied to an electric furnace. v

Fig. 1 shows a detail of the tilting gear. The furnace is shown at Ap-B', B are the spouts for pouring out the slag and metal respectively. A motor C drives a shaft j (Fig. 1) on which is secured a bevel pinion 70 gearing with a bevel wheel Z, thehub of the latter being extended and threaded internally to act as a nut for a screw-threaded rod m which is pivoted at n to the furnace. As the bevel wheel Z is prevented from moving axially its rotation causes the rod m and with it the point of attachment to be drawn up or down and to impart the required tilting motion to the furnace. The wheel Z'is supported ontrunnions Pairs of friction wheels cl, 65 secured to axles f, f of an under frame are rotated, as the furnace is tilted, by rails e, 6 attached to the bed of the furnace.

The rotation of the pairs of friction wheels d d is imparted by roller sets 9., g secured respectively to the shafts f and F, to the pairs of wheels h and 71. or to 72. and k according as the direction of rotation of the tilted furnace forces the rollers g'and g I into contact with the wheels h, 72, or h, if. The wheels of the frame are coupled by links a, 0 0 The dimensions of the rollers and wheels are such that the horizontal movement of the furnace compensates for the change of position of the spout due to tilting, and the contents are discharged in a constant vertical direction.

Having thus described the nature of the said invention and the best means I know of carrying the same into practical effect, ll claim rial can be poured, rails on the receptacle engaging with friction wheels on an under frame, driving wheels on the under frame, the said friction wheels and driving wheels being so proportioned and connected that as the receptacle is tilted in either direction the under frame is moved horizontally, so that the pouring spout of the receptacle remains substantially in a constant vertical plane.
